Premium bus - higher fare, better quality

Some people are willing to pay a higher fare to get a better seat in an airplane. They are called first class and business class.

We can have the same arrangement for a bus. Certain buses can be designed as premium bus by a different color. They will charge 50% more in fare. As they are more expensive, some people will avoid taking the premium bus. Others who are willing to pay the higher fare can be assured of a seat and no crowding. The premium bus should run on the same route as the regular bus.
